Segner (Moon)

Named after Johann Andreas von Segner - German physicist, mathematician (1704-1777).

Segner is a lunar crater located near the southwestern limb , to the northeast of the giant walled plain Bailly. The crater Zucchius is a few kilometers to the south-southwest of the rim, and to the north east lies the unusual formation Schiller. The smaller crater Weigel is located to the east. Segner has a low, worn rim, and is generally much less prominent than the nearby Zucchius. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
